This trial is designed to evaluate the safety and effectiveness of transplanting retinal pigment epithelial cells (RPE) in patients with Age Related Macular Degeneration. The trial is being conducted at the Bundang Medical Center in Gyeonggi-do in conjunction with CHA Bio and Diostech at several centers. Participants will be divided into four groups – each of which will receive different doses of cells. The cells used in the trial have been obtained from human embryonic stem cells. Participants will be monitored for complications including infection and tumour growth, as well as structural evidence of successful engraftment and changes to vision. The trial expects to enrol 12 subjects between September 2012 and April 2016.
